What is in the latest New York Times article?

The paper reports that three people with knowledge of the Goldstone email said it indicated the Russian government was the source of the potentially damaging information on Mrs Clinton.

But the paper says there was no mention in the email of any wider effort by the Russian government to interfere in the election, nor was there any indication of a link to the hacking attack on the Democratic Party that was first reported a week after the meeting.

Mr Goldstone has previously denied any knowledge of involvement by the Russian government.

Lawyer Alan Futerfas, hired by Mr Trump Jr to represent him in the Russia-related investigations, described reports of the meeting as "much ado about nothing" and said his client had done nothing wrong.

What has Natalia Veselnitskaya said now?

She was interviewed on NBC on Tuesday, saying that she "never had any damaging or sensitive information about Hillary Clinton. It was never my intention to have that".

She said the meeting was set up by a man she did not know who told her by telephone to go to Trump Tower.

When asked why Mr Trump Jr seemed to believe she had information about Mrs Clinton, she said: "It is quite possible that maybe they were longing for such information. They wanted it so badly that they could only hear the thought that they wanted."

Ms Veselnitskaya also denied ever having worked for the Russian government.

When was the meeting and how did it come to light?

It took place on 9 June 2016 at New York's Trump Tower, just two weeks after Donald Trump secured the Republican nomination.

It is thought to be the first confirmed private meeting between a Russian national and members of President Trump's inner circle.

After the New York Times first reported the meeting on Saturday, Mr Trump Jr released a statement which confirmed that it had taken place but did not mention whether it was related to the presidential campaign.

Mr Trump Jr said the lawyer then changed subject to the Magnitsky Act and "it became clear to me that this was the true agenda all along".

Adopted by Congress in 2012, the Magnitsky Act allows the US to withhold visas and freeze financial assets of Russian officials thought to have been involved in human rights violations.

Ms Veselnitskaya is married to a Moscow government official and her clients include companies and individuals said to be close to the Kremlin. She has been at the forefront of a campaign - backed by the Russian state - to overturn the act.

In an interview on Monday, Mr Goldstone backed Mr Trump Jr's version of the meeting, saying Ms Veselnitskaya offered "just a vague, generic statement about the campaign's funding" which was "the most inane nonsense I've ever heard".

On Monday, Mr Trump Jr tweeted sarcastically: "Obviously I'm the first person on a campaign to ever take a meeting to hear info about an opponent..." He also denied issuing conflicting statements.

And he linked to a piece in the New York Post headlined "The Times 'exposé' on Donald Trump Jr is a big yawn".

A spokesman for President Trump's legal team said the president was "not aware of and did not attend" the meeting.

Analysis: A grim situation for Trump Jr

Anthony Zurcher, BBC North America reporter

Whether by plan or happenstance, Donald Trump Jr is stumbling into an increasingly dire situation.

The pattern has been set. The New York Times runs a story, Trump Jr issues his response, then the noose tightens.

First he said the meeting with Russian lawyer Natalia Veselnitskaya was about adoption issues. Then the Times reports that Trump Jr thought he would learn damaging information about Hillary Clinton.

The presidential son says he was conducting routine opposition research. Then the Times reports that he was told it was the Russian government itself that was coming to his father's aid.

In a traditional campaign, a foreign government's attempt to offer incriminating information about an opponent - or even the hint of such an overture - would set off all kinds of alarms. The FBI would have been notified. Senior staff would have insulated themselves from incrimination.

The Trump team was not a conventional campaign. And time and time again, it made novice mistakes or, more ominously, took unprecedented risks.

Its candidate prevailed, but it has led to countless political headaches. Now it appears the president's own family, and his presidency itself, could be in peril. They have only themselves to blame.
